Application and m 1, 1910. Serial No. 569,859.

To all whom it may concern:

Be it known that I, J OHN PARKER, a subject of the King of England, anda resident of Philadelphia, in the county of Philadelphia, State ofPennsylvania, United States of America, have invented certain new anduseful Improvements in Spindle-Mountings, of which the following isaspecification.

My invention relates to centrifugal se arating machines of thesuspended, so id spindle type, and the principal objects of theinvention are to constantly lubricate-the ball or roller bearings; toexclude dust and dirt from the latter; to protect the gum bushing fromany possible contact with oil which is a frequent cause of the rottingof the rubber, and to provide a durable and satisfactorily operatingcentrifugal sepa-' rating machine. F

The invention will be claimed at the end hereof, but will first bedescribed in connection with the embodiment, but not the only.embodiment of it, selected; for illustration in the accompanyingdrawings, in which- Figure 1, is an elevational View, partly in section,of a centrifugal separating machine embodying features of the invention,and Fig.2, is a sectional view, drawn to an enlarged scale, of the upperportion of the machine shown in Fig. 1 and illustrating moreparticularly the invention.

The mac ine consists of a drum or basket 1' adapted for receiving thematerial to be purged, said basket being secured to the. lower end of arotating depending shaft or spindle 2 by the nut 3, or in any othersuitable manner. The upper end of said spindle is provided with acup-like enlargement 4:, securely attached to or integral therewith andflanged for connection to a sleeve 5 by the bolts 6 and to this sleeveis secured by the bolts 7, a driving pulley 8, by which the rotation ofthe machine is effected. The sleeve 5 and the cup-like enlargement 4taken together constitute an oil chamber, casing or receptacle.

Within the sleeve 5 at or near the top and bottom of the same areinserted and securely held against independent rotation the outer racesof the annular ball bearings 9 and 10, the inner racesof which aresleeved on a stationary spindle 11, as shown. The weight of the machineand its load is transmitted by the end flange 12 of the sleeve 5 throughthe outer race of the ball bearing [9 and the separator 13 to the stepbearing 14, the lower or stationary race of which rests on a collar 15of the spindle 11. The said spindle passes upward through a collar orsleeve 16 and is secured thereto by a nut 17 and is provided with aspherical projection 18 adapted to a corresponding seat '19 of thesuspension bracket or hanger 20,

thus forming a ball'and socket joint for the supp'ort of the machine andpermitting an oscillation of the spindle and its bearings.

The sleeve 16 carries a rubber buffer or gu'mb'ushing 21 with anadjusting nut 22 ada ted to a seat in the sus ension hanger 20 or thepurpose ofcontro ling the oscillation referred to until the machineautomatically centers itself.

In the construction described all the bearings runcontinuously in an oilbath,the

line of contact of the balls with their races lying outside of the inneredge of the flange 12 and the lower end 23 of the sleeve 16,

the space between these being merely sufficient to provide a workingclearance, thereby providing also a practically dust proofcompartmentfor the bearings. In operation, centrifugal action keeps'the oil fromreaching this clearance to any extent. This compartment-may be drained,however, by the removal of the plug 24:.

- The gum bushing 21 is located above the ball bearings and is thereforemore effective in preventing wide oscillation of the spindle, than wouldbe the case if it were located on the same plane. Furthermore it is alsoentirely free from any possible contact with the oil bath, in which thebearings run and is therefore not in position to be rotted by the actionof such oil.

The term ball bearing is not intended to exclude roller bearings, sothat the latter are intended to be embraced within the claims anddescription so far as they may be substituted for ball bearings.

What I claim is:

1. In a centrifugal separating machine the combination of a supportingspindle, a sleeve surrounding the lower end of same, ball bearingsinterposed between said spindle and sleeve, a driving pulley secured tosaid sleeve, and a solid rotating spindle depending from the sleeve,substantially as specified.

2. In a centrifugal separating machine the combination of a supportingspindle, a sleeve surrounding the same, ball bearings interposed betweensaid spindle and sleeve,

a driving pulley secured to said sleeve and a solid rotating spindlehaving an enlarged cup-like upper end, forming With the sleeve an oilreservoir in which the ball bearings are contained, i

3. In a centrifugal separating machinetlire combination of a suppo'rtinhanger having 'a spherical seat and a bu er seat, a'sup porting spindle,a sleevesurrounding the lower end of said spindle, ball bearings zinterposed between said spindle and sleeve, asecond sleeve or collarsurrounding and secured to the upper end of said spindle and having aspherical projection ada ted to said sphericalseat, and an elastic bu ercarried by said second sleeve and adapted to said louder seat,substantially as described; 7

lln a centrifugal separating machine the combination of a hanger, asolid supporting spindle, a ball joint and louder interposed between thesupporting spindle and hanger,

ma am a solid rotatable spindle provided with a cup-like end surroundingthe end of the supporting spindle, and bearings arranged in the cuplikeend and adapted to rotatably connect the adjacent ends of said spindles.

-5. In a centrifugal separatingmachine the combination of a hanger, asupporting. spindle, a .ball joint and louder interposed be tween thesupporting spindle and hanger, a solid revoluble spindle arranged end toend and in line With the supporting spindle, and bearings for rotatablyconnecting'the adjacent ends of said spindles and fog-insuring alinementthereof, substantially as described.

In testimony whereof l have hereunto signed my name.

JOHN PARKER.
